Immunity and Teeth and gums

1309 capsules across 43 ingredients

Immunity. This page gathers ingredients whose GB register claims relate to the normal function of the immune system, with the exact authorised wording quoted on each ingredient page. Anything not authorised may not be claimed by sellers, and we quote that status too. A balanced diet, sleep and vaccination advice from the NHS come before any capsule.

Teeth and gums. The register authorises wording about the maintenance of normal teeth for several minerals and vitamins, quoted exactly on their pages. Brushing, fluoride and regular check-ups do the real work; the Oral Health Foundation is the specialist charity.

Nothing here is medical advice. The wording is the GB register's, quoted exactly; whether a product qualifies to use it is the seller's responsibility. Speak to a GP or pharmacist before taking a supplement, especially if you are pregnant, take medicines or have a diagnosed condition. Wording from the GB nutrition and health claims register; mapping reviewed 4 September 2026.
